MiniMax H3 API for Unified Video Generation and Editing
Use MiniMax H3 API on ModelFold to turn prompts and multimodal references into polished 2K videos with native stereo sound, consistent motion, and precise creative control.
How MiniMax H3 Expands Multimodal Video Creation
MiniMax H3, also known as Hailuo 03, is an open, general-purpose multimodal video generation system that understands text, images, video, and audio within a unified creative context. It produces 5- to 15-second videos at up to 2K resolution with native stereo audio, while following detailed instructions for characters, actions, camera movement, shot structure, visual style, dialogue, music, sound effects, readable text, and brand elements. Unified multimodal understanding also enables reference-based creation, audiovisual transfer, and precise editing for commercial content production. MiniMax H3 API is now available on ModelFold through three generation methods: Text to Video, Image to Video, and Reference to Video. Developers can select a suitable mode based on available source materials, whether starting from a written prompt, animating a single image or defined first and last frames, or combining multiple image, video, and audio references. View latest MiniMax H3 API documentation on ModelFold for current request parameters, supported input formats, generation settings, and integration requirements.
Build Original Audiovisual Scenes with MiniMax H3 API Text to Video
Text to Video creates a complete audiovisual clip directly from a written prompt without requiring uploaded media. Developers can define the environment, characters, actions, camera direction, shot progression, visual treatment, dialogue, music, and ambient sound in one request. MiniMax H3 API suits advertising concepts, cinematic sequences, animated shorts, motion graphics, social content, and product visuals created entirely from textual direction.
Animate a Single Image or First and Last Frames with Hailuo 03 API
Image to Video supports either one uploaded image or a pair of first and last frames. A single image can act as the starting visual state for natural character motion, environmental movement, and camera animation. Providing both opening and closing frames gives developers clearer control over how the sequence begins, transitions, and concludes. Hailuo 03 API works well for animated posters, product showcases, UI demonstrations, character performances, key-art animation, and structured visual transitions.
Combine Multimodal References Through Hailuo-03 API Reference to Video
Reference to Video combines written instructions with reference images, video clips, and audio files in one generation request. Developers can assign individual assets to character identity, product appearance, motion, camera language, editing rhythm, visual style, voice, or sound design. Hailuo-03 API also supports subject replacement, motion transfer, background modification, relighting, dialogue changes, voice matching, wardrobe updates, product swaps, and localized edits while preserving unaffected parts of the original footage.
What Sets MiniMax H3 API Apart in Multimodal Video Generation
Unified Multimodal Context in MiniMax H3 API
MiniMax H3 API can interpret text, images, video clips, and audio recordings within the same context. Each input can serve a different role, such as defining character identity, guiding movement, establishing camera language, matching a visual style, or providing voice and sound references. This unified understanding helps different creative elements remain connected throughout the final video.
Native 2K Video and Stereo Audio with Hailuo 03 API
Hailuo 03 API generates up to 2K video together with native stereo sound, rather than adding audio through a separate process. Visual action, dialogue, music, ambience, and sound effects can be directed within the same prompt, producing stronger audiovisual continuity and more natural synchronization between what appears on screen and what is heard.
Flexible Multi-Reference Control in Hailuo-03 API
Hailuo-03 API can combine multiple images, video clips, and audio files within one generation. Identity may come from an image, motion and camera behavior from a video, and voice or sound characteristics from an audio reference. Natural-language instructions clarify how every asset should influence the result, reducing conflicts between different reference materials.
Strong Instruction Following and Text Rendering from Hailuo 3.0 API
Hailuo 3.0 API follows detailed directions for shot order, timing, transitions, camera movement, character behavior, sound design, and elements that must remain unchanged.
